[PATCH 1/7] hw/ide: Add the possibility to disable the CompactFlash device in the build

[Thomas Huth <thuth@redhat.com>]

For distros like downstream RHEL, it would be helpful to allow to disable
the CompactFlash device. For making this possible, we need a separate
Kconfig switch for this device, and the code should reside in a separate
file. Let's also introduce a new header ide-dev.h which can be used to
collect definitions related to IDE devices.
